When Santigold dropped her self-titled debut in 2008, it seemed like the promising first act of a fruitful career. Since, though, we've heard more about her infinitesimal name change — she went from Santogold to Santigold after a lawsuit from Santo Gold — than her actual music. Well, she's back now, with a new single dropped via Jay-Z's new site, Life+Times. The perks of signing to Roc Nation Management! It's called "GO," it features Karen O, it was produced by Q-Tip, Switch, and Santigold, it has guitars from Nick Zinner, and it's pretty great. The track — which moves back and forth between a spacey chant that recalls all those M.I.A. comparisons and an instantly catchy pop hook — is about, according to the quickie Q&A that is posted along with the song, "the NEW American dream ... to become rich and famous by happenstance — or sex tapes — and to get there with as little work or talent as possible. And as a result, we are suffering — though many of us don’t know it — as quality becomes a notion of the past. We’re ruining art, our planet, and our health, all due to our newfound obsession with instant gratification, with the short term quick-fix." Just so you know!
